Cats + nice guitars seldom mix well, from my experience. Mine has never actually done damage to my guitars, but it will chew off the rubber leg covers on guitar stands...and eat off the foam that is inside the headstock cradle if they can get to it. Cats are curious, by nature...much more so than dogs. If it smells good to them, they just can't help but to mess with it...and they are not aware of how sharp their claws are.
I just don't leave my guitar or stands in the living room where he can get at it.
And...sorry about the damage on your guitar!
